Based on multiple reports, I think a more accurate headline would be “Packers to request an interview”, which is a little different. Since he has connections to Packer management, it is possible, but a non-denial could also mean he is using the Packer interest to negotiate for something like an increase in his assistants’ salary budget.
Fitz is his own man, and may interview, but I would not consider it a certainty until it happens. It is possible that next week a Chicago Trib headline says, “Fitz turns down Packer interview, declares NU his Dream Job.” If you are the parent of a high school sophomore with great football skills and academic chops, I think that headline might make you think of Evanston as a destination rather than Pali Alto.
